Penn Science Cafe

Hauling science out of the lab for a night on the town, the Penn Science Café offers the Philadelphia region an opportunity to pitch questions to leading scientific experts who drop the jargon to explain their work in layman's terms. All Penn Science Café events are free and open to the public.

Upcoming events in this series:


6:00 pm - 7:00 pm
Alain PlanteAssociate Professor, Earth and Environmental StudiesThe Carbon Beneath Our Feet World Cafe Live, 3025 Walnut St.

There is more carbon in the earth’s soils than in the atmosphere and plants combined. There is also six times more carbon exchanged annually between soils and the atmosphere, primarily as carbon dioxide, compared to annual fossil fuel emissions. Yet, as Leonardo DaVinci said, “We know more about the movement of celestial bodies than about the soil underfoot.” In this talk, Associate Professor of Earth and Environmental Science Alain Plante will describe the role soils play in the global carbon cycle and in sustainable agriculture and land use.

Expert faculty from the University of Pennsylvania shed light on their research at the Penn Science Café. It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.

Presented by Penn Arts and Sciences in partnership with the Office of University Communications, Penn Café events are free and open to the public, but RSVPs are encouraged. For more information or directions, contact Gina Bryan at 215-898-8721 or email at
